HEATING-STOVE.

To (ZZZ whom it may concern:

Be it known that I, ALAN L. JERVEY, a citizen of the United States,residing at Richmond, in the county of Henrico, State of Virginia, haveinvented certain new and for its object to provide a stove soconstructed as to present a materially increased heat ing surface to thefire and a correspondingly increased radiating surface to the outer airwith an arrangement of parts which will facilitate the circulation ofcold air about the stove to prevent burning of the metal thereof.

Another object is to provide a stove having these characteristics yetwhich will be of such structure that it may be cheaply manufactured andquickly assembled.

Other objects and advantages will be understood from the followingdescription.

In the drawings: Figure 1 .is a vertical section through the stove; Fig.2 is a side elevation, the outer shell being partially broken away;.Fig. 3 is a transverse section on line 33 of Fig. 1; Fig. 4 is afragmentary section on line 4-4 of Fig. 1, showing the wall-receivinggrooves; Fig. 5 is a section through the flue casting on line 5-5 ofFig; 1, with the parts inv perspective; Fig. 6 is a top plan partlybroken away: Fig. 7 is a fragmentary section on line 7--7 of Fig. 1looking upwardly; Fig. 8 is a section on line 88 of Fig. 1, and Fig. 9is a side elevation of the drum removed.

Referring, now, to the drawings the present invention comprises a bodyportion, a, which includes top and bottom members 5 and 6 between whichthere is engaged an outer cylindrical wall portion 7 and an inner wallportion 8. This wall portion 8 is convoluted to produce a plurality ofvertically extending hollow radial fins 12, which surround a centralcylindrical chamber 10, the interiors 11 of the fins communicating withthe chamber.

The top and bottom members 5 and 6 are provided with grooves 13 whichreceive the edges of the fins therewithin, the members 5 and 6 thusserving to close the ends of the Specification of Letters Patent.

fins. Between the fins, the members 5 and 6 are provided with openings14.

The top member 5 hasa central opening 15 which lies with its edges justinwardly of the inner ends of the fins. This opening communicates withthe chamber 10, and through it fuel may be introduced to the chamber, aswill be understood.

The bottom member 6 is provided with a depression 16, circular in formand lying just within the inner ends of the fins. Centrally of thedepression 16 the bottom member has an opening 17 receiving a depend ingstem 18 carried-by a grate plate 19 centrally thereof. The grate platelies within the depression 16 and this plate is provided with aplurality of openings 20 arranged for registration with openings 21formed in the bottom of the depression. A horizontal lever 22 is engagedwith the stem 18 and extends laterally beneath the stove and through themedium of this rod the plate 19 may be operated to bring its openings 20into and out of registration with the openings 21 to shake the fire. i

The wall portion 8 has an opening 23 therein at its upper portioncommunicatingv with the chamber 10 and in this opening there is set afiue casting 24 having a passage 25 therethrough communicating at itsinner end with the chamber 10 and opening outwardly of the wall portionat its outer end. This flue casting is provided with grooves 26 in itsunder face for the reception of the upper edges of the fins 12 which lietherebelow and is further provided with draft passages 26 communicatingwith the interiors of the adjacent fins. The top and bottom members haveperipheral flanges 27 extending beyond the outer extremities of the finsand embracing the outer cylindrical shell 7 whereby to retain same inposition.

A perforated closure 28 is removably disposed in position to close theopening 15 and this closure carries a depending drum 29 lying within thechamber 10 and extending below the flue casting 24. The lower portion ofthis drum 29 is cylindrical in horizontal section and lies in closerelation to the inner ends of thefins 12, but at its upper portion thedrum is circumferentially constricted as shown at 30 to produce apassage 31 surrounding the upper portion of the drum, and with which thepassage 25 of the flue casting 24 communicates. It will also be seenthat the chambers 11 within the fins 12" Communicate with the passage 31at their upper portions and since the lower part of the drum 29 blocksthe upper part of the chamber 10, the bottom of this drum will act as aflame and heatspreader to direct the flames from the fuel within thechamber 10 into the chambers 11 of the fins; The products of combustionwill of course be so deflected also and will pass up through thechambers 11 around the lower portion of the drum 29, and then throughthe passage 31 to the flue casting, by which they will be carried off.The openings through the closure 28, indicated at 28, communicate withthe interior of the drum 29 for the egress of heated air from the drum.

The top and bottom members are secured to the wall portion 7 by bolts 33engaged through the flanges 27 and through the ends of certain of thefins, though it will be understood that these bolts may be located atany suitable position. If desired the outer wall portion 7 may beprovided with a plurality of perforations or apertures 34 through whichthe heated air will be gradually radiated, and this wall may further besuitably ornamented or decorated so that the general appearance of thestove will be enhanced.

From the foregoing it will be seen that the present invention provides astove in which by reason of the convolutions of the wall portion, thereis presented a greatly increased radiating surface and a greatlyincreased heating surface, and that the heat from the fire is broughtinto contact with the heating surface by reason of the fact that allproducts of combustion are deflected into the fins by the drum 29. Thefact that air is free to circulate between the fins causes rapidradiation of heat from the fins and thus prevents burning of the wallportions.

Obviously when the stove is in operation,

cold air will enter through the'openings 14 in the bottom member 6,travel upwardly between the fins 12 where it is raised to a relativelyhigh temperature, and pass outwardly through the openings in the topmember 5 and perforations 34 in the wall 7 It may further be stated thatthe drum 29 may be partially filled with water as indicated at 35 inFig. 1, whereby the air rising therefrom and from the fins will beconstantly moistened, dry heat being in this with inwardly openingvertical passages and" having a combustion chamber therewithin,

a flue adjacent the upper end of the casing communicating with thechamber, and a heating drum removably mounted in the chamber and openingthrough the top of the casing, the cross dimensions of'the bottomportion of the drum being approximately equal to those of the chamberwherebyto arrest and deflect the products of combustion into thevertical passages,while the upper portion of said drum is constricted toprovide a surrounding passage communicating with the flue and with thevertical passages.

In testimony whereof, I affix my signature, in the presence of twowitnesses.
